Application Sled liovsmber 5, 1906. Serial No. 322,858.

To all whom it may concern.-

Be it known that l, BENJAMIB A: Chow, e citizen of the United States, residing at August-e, in the county of Richmond and tote of Georgi-s, have invented certain new snrlusefui Improvements in Cotton-Pickers; and I do hereh y declare the folio-sing to be a full, clear, and exact description of the some, reference being had to she accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates .to iii-pickers of that type wherein the cotton detached from the bolls by mechanical sue-ens directed by the hand of an attendant and when dotached is conveyed to e suitable rece tacle, t-he conveying means usually ens preferably employed consisting of a flexible conduit through which the cotton is drown-by sir-suction.

The object of the inventio of this application is to improve the iclicr or nozzle portion of the picker descrihed in my contemporaneous application, Serial Yo. 318,31, filed May 23, 1906, and hence the drawings illustraiie simply the said portion of the eppsratus.

In the drawings, Figure tion of a picker-nozzle emho' improvements. Fig. 2 is sbe Fig. 3 is a section longitudiii zle.

Similar letters of reference she several figures indicate like per-cs.

The flexible pipe or conveyer-duct is indicated by the letter A and its nozzle end by the letter B. The nozzle end is provided with twoppenings, one in line with she conduit for the admission of sir clone and the size of which may be regulsieo. by a disk or e present len View, 5 the nozother suitable vzilve C, adopted to be controlled by the attendant bl ou h a handle or finger-p ece C. The or or cottonsdmissionopening inthe nozzle is e transverse opening through which cotton is pushed by the mechanically tions of the picker, so as to fcsce the some into the air-current by which it is carried to the common receptacle. 1

The cotton admission opening is surrounded by e hell-rnouth iron l which for the sake of lightness may be 5.1 aluminium casting. The bell-mouth siren 1e is provided with projections D, in which are hearings for saw or picker shafts s'rrenged in e.

quadrangle and connected in series by bevelgesrs E. Each shaft carries a saw or picker F, which on one side projects into the hell-mouth, the diameter of the saws and the location oi? the shafts being such that the edges of the sons or pickers project into the or conduit itself and. pass out through narrow slits, whereby the air-current Will effectually clear or clean the saws, and no other clearing means is usually found necessary or desirable.

Portions l) of the hell-mouth frame preferably extend around the sows to protect the seine; but the sews are exposed at points in proximity to the hell-mouth to facilitatethe entanglement of the cotton. The edge of the hell-mouth preferably terminates Withigi the peripheries of the sews or ickcrs. In other Words, the peripheries of tie saws or pickers project eyond the edge of the bell-mouth to entangle the cotton; but by reason of the fact that these portions of all the pickers more toward a. common center the cotton is carried to the center of the bellmouch and enters the some before the airsuction materially ni'l'ect-s the same. As & resule the lishility of picking up leaves, trash, and dirt, which will entsn le with the sews, is very much reduced. The sews, it will be noted, are preferably seii with the teeth rcrcrsely inclined to their direction of rotation, and this is preferably the case regardless of whether the teeth aresolid or pivoted, as heretofore been proposed. With the teeth so set chey will successfull entangle the cotton, but operate to repel e1 nistier not of e. fibrous nature.

In the resent arrangement one of the shafts E is in line with the power-shaft H and may be directly connected thereto, thus reor she hell-mouth in position to direct the inzindle L of any suitable concoining sir against the lint in c direction iending to release the some from the sews.

Spri

verseiy into said tin-passage, of toothed roi, secured to the inside of the bell mouth on each side oithe sews, may also be in remoxin the lint from or is neuinntic cotton-picl er theconn 1h the nozzle lnwlng e substan- .1 pa. ge, oi toothed rotary pickers journn. d at an angle to each other around the bellanouth end having their ieripheries projecting into both the bell-mouth end the suhstentinily straight passnge through the ntnzzlc or mechanically carrying the cotton entirety through the bell-mouth and delivcn inq the seine into the passage.

i5. in e pneumatic cotton-picker the corn hinnlion with the nozzle having an unpassage th iroughniid n. hell-mouth cottonentrzn e at one side of and opening transtnry pickers journnled et an angle to each other ound the bell-mouth, said pickers being of greater disin'ieter than the length of the bellnnouth, and having their peripheries pro.- jecting into the bell-n1outh and beyond. eaich end of the seine, whereby the cotton will be engaged before it enters the bell-mouth and will no carried by the pichers entirely through the hell-mouth and into the air-passage.

3. in a cotton picker, the ponlbinntion with the nozzle end. of thedu ct -having it valved air-inlet and 22 transrerse eotton inlet, of n bell-mouth frznne secured-to one side of the nozzle around the QOttODrilllCt and huvin shaft-twining: proections on four sides thereof, picker-she lse'nd plCliCl'SjOJlPlltllQd in said 4 bearings and connected by gearing for siinultan ous rotation and a. pmver-shnlt mounted in t nont "with one of said picker-shafts.
